Larry David has a habit of referencing people he knows in Curb Your Enthusiasm and, now, in his first HBO movie, Clear History, out Aug. 10.

A valuable painting his character owns and loves -- of a shopping cart -- constantly is referred to as "a Plepler," named for HBO CEO Richard Plepler. "It was more that it's a funny-sounding name," explained David to THR at the July 31 L.A. premiere.
